a discovery.

in an attempt to demonstrate something to my somewhat technically challenged sister, we switched the SIM cards in our cell phones this afternoon. this let to a fascinating and completely unexpected discovery: my phone's firmware appears to be unlocked. while hers complained about being loaded with a cingular SIM, mine happily accepted her t-mobile SIM, signed onto the network, and made calls.

what does this mean? well, nothing really as far as practical considerations. theoretically, it means, should i ever find myself stranded in europe, i could purchase a pre-paid SIM and use my phone on the european networks. which is kind of a cool thought.
